WebHow does Spectral Band Replication works? SBR does not really encode the highest part of the frequency spectrum; it reconstructs this part. In a 64 kbps Mp3Pro encoded file, around 60 kbps are used for the conventional Mp3 data. The Mp3 encoder encodes the music signal up to 8kHz in a conventional way.
